L'Oréal Professionnel Keratin Alpha Sleek Hair Serum is built on a 5% Keratin Sealer that coats the hair fibre to lock down the cuticle, working alongside dimethicone and amodimethicone to deliver smoothness, shine and humidity protection up to 80%.
Apply two to eight pumps to towel-dried hair depending on thickness, distribute through lengths and ends, then blow-dry to activate. It suits frizz-prone or coarse hair wanting a long-lasting, mirror-like finish and heat protection up to 230°C.
